Adjust next group of photoelectric sensor（6）, midget relay and electrically-controlled liquid crystal light modulation plate（8）, make next group of electrically-controlled liquid crystal light modulation plate
（8）Continue to be in the light, until vehicle avoids strong light safety；
Following steps are specifically included in debugging during light-blocking region：
B1：Vehicle is driven at design monitoring shot-light maximum distance, the electrically-controlled liquid crystal light modulation of light-blocking region corresponding position in adjusting
Plate（8）Corresponding photoelectric sensor（6）Angle, make the photoelectric sensor（6）Detect shot-light light or traffic light；
B2：Photoelectric sensor（6）Corresponding midget relay action, the electrically-controlled liquid crystal light modulation plate of upper light-blocking region bottom（8）Control
Electrode (10) voltage processed declines, and becomes translucent, blocks the shot-light light for injecting human eye；
B3：Simulating vehicle is reduced, monitored on shot-light incidence point by monitoring the process in shot-light area, the distance of vehicle and monitoring shot-light
It moves, when incidence point is moved to the electrically-controlled liquid crystal light modulation plate of bottom（8）Edge when, extend photoelectric sensor（6）Outer tube
（6-5）, make photoelectric sensor（6）It can't detect incident light, corresponding electrically-controlled liquid crystal light modulation plate（8）Recover transparent；
B4：Repeat the electrically-controlled liquid crystal light modulation plate of the adjusting corresponding position in step B1 ~ B3（8）Corresponding photoelectric sensor（6）'s
Method adjusts next group of photoelectric sensor successively（6）, midget relay and electrically-controlled liquid crystal light modulation plate（8）, make next group of automatically controlled liquid
Brilliant dimmer board（8）Continue to be in the light, until vehicle avoids monitoring shot-light light safety.
7. automobile-used electrically-controlled liquid crystal light modulation subregion light barrier control method according to claim 6, it is characterised in that：Described
Design left front maximum distance is 100m, and design monitoring shot-light maximum distance is 40m.
8. automobile-used electrically-controlled liquid crystal light modulation subregion light barrier control method according to claim 6, it is characterised in that：Step A2
Described in multiple electrically-controlled liquid crystal light modulation plates（8）Center spacing is 66mm.
